Ah, well, it's not a Foundation Class, but this is the
whole purpose of my program XWINDOW.

http://www.dfanning.com/programs/xwindow.pro

I *always* want resizeable graphics windows that can send
the contents of the window to a PostScript, JPEG, GIF file
etc. Here is a program that can do that for *any* IDL
graphics procedure (including any you care to invent) if
they follow four simple rules:

(1) Are not defined with more than three positional
parameters. (An unlimited number of keywords are
allowed.)

(2) Are defined with an _EXTRA keyword.

(3) Do not open their own windows.

(4) Do not use a "DEVICE, DECOMPOSED=0" command. (This
is a new limitation and was exposed by the way colors
now work on the PC. :-)

For example, you could use it with the SHADE_SURF command
like this:

IDL> XWindow, 'Shade_Surf', dist(40), /XColors, /Output, $
Shades=BytScl(dist(40), Top=!D.N_Colors-1), AZ=45

Note, this program needs three other programs from my
library to work properly:

http://www.dfanning.com/programs/xcolors.pro
http://www.dfanning.com/programs/pswindow.pro
http://www.dfanning.com/programs/ps_form.pro

Taken as a whole, these programs are a "foundation class"
for constructing a whole variety of applications. (I have,
perhaps, just given away the whole store with respect to
a very lucrative consulting business. Oh, well, now that
I know how to print object graphics programs I can get into
that line of work. :-)

Cheers,

David
